Dr Matt O’Callaghan is an ecologist specializing in stream and floodplain invertebrate responses to disturbance. His current research is investigating the impact of drought on the functioning of stream ecosystems, part of a NERC funded project led by Dr Mark Ledger.
2007-2011 PhD Floodplain ecology. University of Birmingham
2004-2007 BSc (Hons)Environmental Science ( 1st Class) University of Birmingham
Dr O’Callaghan completed an Environment Agency funded PhD on specialist insect communities in floodplains, using stable isotope techniques to investigate the role of flood risk on prey selection and resource partitioning (supervisors Professors Jon Sadler and David Hannah). Following his PhD he worked with Professor Jon Sadler and James Hale developing new modeling techniques to assess urban ecosystem functioning. He is currently a Research Fellow, working with Dr Mark Ledger on a NERC funded project to investigate the impact of drought on stream ecosystem functioning.
